WIRE-WORKING MACHINE.

Application filed January 26, 1,923. Serial No.-6 15, 1 58.

To all whom it may concern:

Be it known that 1, AH LEON STANLEY Yo, a citizen of China, and a resident of Hong Kong, China, have invented certain new and useful Improvements in Vvireworking Machines, of whichthe following is a specification. I

The present invention relates in general to 'wire"working machines, andm'o'reparticularly to an improved wire working machine especially adapted for use in the pro-' duction of hat frames or the like.

The object of the invention is to provide an improved machine of this character which unites the elements of the hat frame positively and securely and eliminates the necessity of manually wrapping these elements with wire, which is rapid and certain in its operation, which is of simple and durable construction, reliable in operation, and easy and inexpensive to manufacture, and which has a wide range of utility.

Other objects and advantages of the invention'reside in certain novel features of the construction, combination and arrangement of parts which will be hereinafter more fully desc'ibe'd and particularly pointed out in the appended claims, reference beingjhad to the accompanying drawings forming part of this specification, and in which: Y

Figure 14 is a view, illustrating a some whatfdili'erent joint which maybe produced by the present invention.

' Qeferring' to the drawings wherein for the sake of illustration is showntlie preferred embodiment of the invention, the numeral 10 designates a central post, upon which the bed or work table for the wires designated generally at 12 is arranged. The bed or work table 12 includes a stock or sleeve'13 having .a limited movement on the post 10 and a fixed-section l lsecured by means of ascrew or the like15 to the central post 10 and having tongue and groove'connection 16 with the mainportion or section of the sleeve or stock. I,

The slidable sleeved?) is urged outwardly on the post 10 to the position shown in'Figures 1, 2 and 4 by means of a coil spring 18 arranged on thepost and abutting the sleeve 13 at one end and a'collar 19 at its'other end. The collar "19 isfixed to the post 10.

The fixed section 1 14. ofthe' stock .or sleeve is slightly longer thanthe majorjportion thereof and projects from one end of the sleeve to provide'a' 'head21; the head 21 beingformed "with a transverse guide opening 2l thr'ough which the crimpingor tie wire is inserted. (The 'head'21 also constitutes an element of the cutting means "for" the tie wire, as will hereinafter more fully appear. Diametrically' opposite the'heafd 21a lug 22 is integrally formed with the stockorsleeve 14 and is adapted to engage the end of the tie wire inserted through the opening 21 thereby serving as a stop '01 gauge for the tie wire. The end of thestockat which the head 21' and lug' 22 are located and which is designated generally-at23 constitutes the work table proper, and it is divided by the head 2l' and lug 22 iiitosections' 2 L and25. The section 24 is provided with radial grooves 26 and 27 and the section 25 is provided with radial grooves 28 and 29 which are alined with the radial grooves 26 and 27, respectively, being directly opposite, so that the alined grooves are complementary to each other, and the complementary grooves constitute seats or holders for the wires. The stock 13 is provided with radial ribs 30, 31, 32 and 33 ex tending from the stock below and in alinement with the grooves 26, 27, 28 and. 29, respectively and having their top edges or surfaces coplanar with the bottoms of the grooves so that these ribs serve to enlarge the seats presented by the grooves and to afford a positive support for the wires for the major portion of their extent within the stock.

It is to be noted that the radial ribs 30, 31, 32 and 33 extend only part of the way toward the center and leave a circular or cylindrical space 38 in which the stationary die'or anvil 40 is adapted to be arranged in the operation of the machine. The stationary die or anvil 40 is removably fitted in the end of the post 10, the screw 15 being advantageously utilized for this purpose, as shown in Figure 3, although a separate screw or other releasable fastening means may be employed, if desired. The anvil die 40 is provided with a grooved die face 4O which operates upon the tie or crimping wire in a manner which will hereinafter be more fully described. it is to be understood of course that the stationary die does not move but the stock mounted on the base does move so as to bring the stationary die within the space 38.

A movable die 41 is provided and includes bits 43 and 44 having notches or kerfs 45 and 46 therein which receive the portions of the wire to be bent or shaped. The circumferential edge 43 of the bit 43 also constitutes a cutter, being cooperable with the head 21 to sever the desired length of tie wire. The

body of the movable die is slotted 1ongitudi-,

nally to accommodate the ribs 30, 31, 32 and 33 as well as the wires carried thereby.

In the operation of the die as thus far described, the wires W and W of the hat frame which are to be united or connected are arranged on the seats constituted by the complementary notches and the alined ribs. The binding or tie wire T that is to be bent around the wires to be united is inserted through the opening 21 of the fixed section of the stock far enough to reach completely across the opening of the fixed die and until it touches part 22.- One instance or illustration of wires so arranged is shown in Figure 4.

The movable die is then forcibly urged toward the stationary die. The first phase in the action whichfollovvs is the cutting of the requisite length of tie or binding wire T which is accomplished by the circumferential cutting edge 43 of the bit 43 which coacts with the head 21 for this purpose. After this first phase of the, operation has been completed the wires are related as shown in Figure 10 that is with the wires and W crossing and the severed length of the tie or binding wire overlying the crossing of the wires W and W. While the cutting action is being carried out the bit 43 as well as the bit 44 is engaged with the tie wire and following the severance of the requisite length of the tie wire the severed length is bent around the crossed wires W and W. this bending being carried out by the bits vuntil the binding or tie wire assumes the U- shaped form shown in Figure 11. During the severing of the requisite length of the tie wire and during the initial bending thereof, the movable section or sleeve 13 of the work table is held substantially stationary on the post 10 by the coil spring 18 and the movable die moves inwardly of the sleeve 13, the longitudinal slots of the movable die accommodating the wires to be united and the ribs on which these wires are positively supported. Vhen, however, the initial bending of the tie wire has been completed, the inner end walls of the longitudinal grooves of the movable. die 41 engage the portions of the wires which are positively supported on the ribs 31, 32, 33 whereby any subsequent movement of the movable die is transmitted to the sleeve 13 and the same is moved along the post 10 against the action of the coil spring 18 in order to permit the movable die 41 and the stationary die 40 to coact to complete the bending of the tie wire as will now be described. At this time the ends of the binding wire are disposed immediately adjacent the curved or inclined walls of the grooves of the die face of the stationary die so that as the relative movement between the dies progresses these ends will be engaged by the inclined or curved walls of the grooves of the die face and the binding wire will be bent around the wire W as shown in Figures 9, 12 and 13, thus completing the joint.

A gage is organized with the machine and comprises a sliding frame 50 including parallel sidebars 51 slidably mounted in guideways 52 provided in the collar 19 and held therein by means of a washer or the like 54 fixed to the post 10. A set screw 55 secures the sliding frame in adjusted position. One of the lateral faces of the sliding frame is provided with graduations 56 which provide for the accurate adjustment of the gage. The gage carries a bar 57 disposed at right angles to the sliding frame and having its upper end provided with a central slot 58 which receives one of the elements of the hat frame.

In order to provide for the formation of also provided with] a-.: groove- 60. intermediate the grooves 26'and 27 'and'c'onstitutin'g a seat for the wire T. In addition zto t'he longitudinal groove in i the movable =die which accommodate the ribs '30 to 33, inclusive, as well as the wires carried thereby, this movable die is also provided with a groove 61 which coact-s with the groove 60 in the formation of thejoint'sh'ownin Figare 14. As shown in-this figure three wires W, W and T, such as are'found in the center'of the top of ahat-frame, are bound'together. The-third wire T"is itself looped over across the other two wires and functions as the tying or' binding-wire.

Informing this joint the wires W and W are arranged on the. seatscon'stituted by the complementary notches :and the alined ribs and the wire T is received in the groove 60 and has its end extending over'the crossing of the wires lV and W and just beyond the same. The movable die 41 is then brought in such angularrelation with .the stationary die that the groove '61 of the die 40 is alined with the groove '60- of the stock, the bits43 311C144: being aline'd with the head 2]. and lug 22' respectively, ?and thus being idle during the operation. The movable die t1 includes however a-third 'bit or die face designated at 63, which engagesthe end of the wire T extending beyond the crossing of the wires W and VVand bends ,thisprojecting end ofth wire T dow'n-intoengagement with the underlying groove of the die face 40 'whereby-the wire T islooped around the wires 'W and W- as shown in Figure 14.
